Julia Creek dunnart

Sminthopsis douglasi

Blamed on cats

IUCN Status: Near Threatened

EPBC Threat Rating: Very high

IUCN Claim: “Exotic predators (especially cats and foxes)’”

Studies in support

Cats hunt Julia Creek dunnarts (Kutt 2003; Kutt 2011; Kutt 2012; Mifsud & Woolley 2012).

Studies not in support

Cats do not select for Smithopsis spp. (Kutt 2012).

Is the threat claim evidence-based?

There are no studies linking cats to Julia Creek dunnart populations.

Evidence linking Sminthopsis douglasi to cats. Systematic review of evidence for an association between Sminthopsis douglasi and cats. Positive studies are in support of the hypothesis that cats contribute to the decline of Sminthopsis douglasi, negative studies are not in support. Predation studies include studies documenting hunting or scavenging; baiting studies are associations between poison baiting and threatened mammal abundance where information on predator abundance is not provided; population studies are associations between threatened mammal and predator abundance.
